(a) and (b) Single-molecule TERS spectra for an isolated H2TBPP molecule adsorbed on the terrace or at the step edge. (c) and (d) Calculated TERS spectra of H2TBPP. The inset image in (a) shows the schematic image of tilted H2TBPP molecule with tilt angle of 30°. The inset image in (b) shows the schematic image of a flat-lying H2TBPP molecule.
